These parameters may be left at their default values, but note that the board thickness value will be used when exporting a 3D model of the board, and solder paste shapes of pads on the board. These values will be added to any clearance overrides set on individual footprints or pads. Positive clearance values will result in the shape of the solder mask copper shape. Negative clearance values will result in the opening being smaller than the copper shape. WARNING Most commercial PCB fabricators expect these values to be zero and make their own adjustments
